The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or becomes stuck, the control board cannot verify safe flue conditions, resulting in a no-heat lockout — often with a fault code indicating a pressure switch error. Common symptoms include the inducer motor running continuously with no ignition, or the furnace cycling off immediately after startup.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC061 | Factory-calibrated W.C.
